On the 13th July, Prince Maurice took command of the States' forces, 13,000 foot and 3000 horse, with thirty pieces of cannon, assembled at Schenkenschans. The July English and French regiments in the regular service of the United Provinces were included in these armies, but there were no additions to them: "The States did seven times as much," Barneveld justly averred, "as they had stipulated to do." Maurice, moving with the precision and promptness which always marked his military operations, marched straight upon Julich, and laid siege to that important fortress. The Archdukes at Brussels, determined to keep out of the fray as long as possible, offered no opposition to the passage of his supplies up the Rhine, which might have been seriously impeded by them at Rheinberg. The details of the siege, as of all the Prince's sieges, possess no more interest to the general reader than the working out of a geometrical problem. He was incapable of a flaw in his calculations, but it was impossible for him quite to complete the demonstration before the arrival of de la Chatre. Maurice received with courtesy the Marshal, who arrived on the 18th August, at the head of his contingent of 8000 foot and a few squadrons of cavalry, and there was great show of harmony between them. For any practical purposes, de la Chatre might as well have remained in France. For political ends his absence would have been preferable to his presence.

Maurice would have rejoiced, had the Marshal blundered longer along the road to the debateable land than he had done. He had almost brought Julich to reduction. A fortnight later the place surrendered. The terms granted by the conqueror were equitable. No change was to be made in the liberty of Roman Catholic worship, nor in the city magistracy. The citadel and its contents were to be handed over to the Princes of Brandenburg and Neuburg. Archduke Leopold and his adherents departed to Prague, to carry out as he best could his farther designs upon the crown of Bohemia, this first portion of them having so lamentably failed, and Sergeant-Major Frederick Pithan, of the regiment of Count Ernest Casimir of Nassau, was appointed governor of Julich in the interest of the possessory princes.

Thus without the loss of a single life, the Republic, guided by her consummate statesman and unrivalled general, had gained an immense victory, had installed the Protestant princes in the full possession of those splendid and important provinces, and had dictated her decrees on German soil to the Emperor of Germany, and had towed, as it were, Great Britain and France along in her wake, instead of humbly following those powers, and had accomplished all that she had ever proposed to do, even in alliance with them both.

The King of England considered that quite enough had been done, and was in great haste to patch up a reconciliation. He thought his ambassador would soon "have as good occasion to employ his tongue and his pen as General Cecil and his soldiers have done their swords and their mattocks."

He had no sympathy with the cause of Protestantism, and steadily refused to comprehend the meaning of the great movements in the duchies. "I only wish that I may handsomely wind myself out of this quarrel, where the principal parties do so little for themselves," he said.

De la Chatre returned with his troops to France within a fortnight after his arrival on the scene. A mild proposition made by the French government through the Marshal, that the provinces should be held in seguestration by France until a decision as to the true sovereignty could be reached, was promptly declined. Maurice of Nassau had hardly gained so signal a triumph for the Republic and for the Protestant cause only to hand it over to Concini and Villeroy for the benefit of Spain. Julich was thought safer in the keeping of Sergeant Pithan.

By the end of September the States' troops had returned to their own country.

Thus the Republic, with eminent success, had accomplished a brief and brilliant campaign, but no statesman could suppose that the result was more than a temporary one. These coveted provinces, most valuable in themselves and from their important position, would probably not be suffered peacefully to remain very long under the protection of the heretic States-General and in the 'Condominium' of two Protestant princes. There was fear among the Imperialists, Catholics, and Spaniards, lest the baleful constellation of the Seven Provinces might be increased by an eighth star. And this was a project not to be tolerated. It was much already that the upstart confederacy had defied Pope, Emperor, and King, as it were, on their own domains, had dictated arrangements in Germany directly in the teeth of its emperor, using France as her subordinate, and compelling the British king to acquiesce in what he most hated.

But it was not merely to surprise Julich, and to get a foothold in the duchies, that Leopold had gone forth on his adventure. His campaign, as already intimated, was part of a wide scheme in which he had persuaded his emperor-cousin to acquiesce. Poor Rudolph had been at last goaded into a feeble attempt at revolt against his three brothers and his cousin Ferdinand. Peace-loving, inert, fond of his dinner, fonder of his magnificent collections of gems and intagli, liking to look out of window at his splendid collection of horses, he was willing to pass a quiet life, afar from the din of battles and the turmoil of affairs. As he happened to be emperor of half Europe, these harmless tastes could not well be indulged. Moon-faced and fat, silent and slow, he was not imperial of aspect on canvas or coin, even when his brows were decorated with the conventional laurel wreath. He had been stripped of his authority and all but discrowned by his more bustling brothers Matthias and Max, while the sombre figure of Styrian Ferdinand, pupil of the Jesuits, and passionate admirer of Philip II., stood ever in the background, casting a prophetic shadow over the throne and over Germany.

The brothers were endeavouring to persuade Rudolph that he would find more comfort in Innsbruck than in Prague; that he required repose after the strenuous labours of government. They told him, too, that it would be wise to confer the royal crown of Bohemia upon Matthias, lest, being elective and also an electorate, the crown and vote of that country might pass out of the family, and so both Bohemia and the Empire be lost to the Habsburgs. The kingdom being thus secured to Matthias and his heirs, the next step, of course, was to proclaim him King of the Romans. Otherwise there would be great danger and detriment to Hungary, and other hereditary states of that conglomerate and anonymous monarchy which owned the sway of the great Habsburg family.
